Python：将您上次的答案乘以一个常数

Question

我正在尝试展示特定年数内，随着每年增加的百分比，薪水的变化。

print('Enter the strting salary: ', end ='')
SALARY = float(input())
print('Enter the annual % increase: ', end ='')
ANNUAL_INCREASE = float(input())

calculation1 = ANNUAL_INCREASE / 100
calculation2 = calculation1 * SALARY
calculation3 = calculation2 + SALARY



Yearloops = int(input('Enter number of years: '))

for x in range(Yearloops):
    print(x + 1, calculation3 )

在将工资设为25000元、涨幅设为3%、年数设为5年后，这是我的输出结果。

1 25750.0
2 25750.0
3 25750.0
4 25750.0
5 25750.0

我需要再次将上一个答案乘以增加的百分比。应该像这样：

1 25000.00 
2 25750.00 
3 26522.50
4 27318.17 
5 28137.72

有人可以展示给我如何做吗？谢谢。

Answer 1

你需要将计算放在for循环内部，这样它才会每年发生一次，而不仅仅是一次。

salary = float(input('enter starting salary: '))
annual_increase = float(input('enter the annual % increase: '))
years = int(input('enter number of years: '))

for x in range(years):
    print(x + 1, salary)

    increase = (annual_increase/100) * salary
    salary += increase

输入25000、3%和5年，输出：

1 25000.0
2 25750.0
3 26522.5
4 27318.175
5 28137.72025

稍微修改一下您代码的版本：

print('Enter the strting salary: ', end ='')
SALARY = float(input())
print('Enter the annual % increase: ', end ='')
ANNUAL_INCREASE = float(input())

Yearloops = int(input('Enter number of years: '))

value = SALARY
for x in range(Yearloops):
    print('{} {:.2f}'.format(x + 1, value))
    value = value * (1 + ANNUAL_INCREASE/100)

使用测试用例25000、3、5将产生以下输出：

Enter the strting salary: 25000
Enter the annual % increase: 3
Enter number of years: 5
1 25000.00
2 25750.00
3 26522.50
4 27318.17
5 28137.72

Answer 3

我觉得这个会满足你的需求：

print('Enter the strting salary: ', end ='')
SALARY = float(input())
print('Enter the annual % increase: ', end ='')
ANNUAL_INCREASE = float(input())

calculation1 = ANNUAL_INCREASE / 100

Yearloops = int(input('Enter number of years: '))

newsalary = SALARY
print(1, newsalary )
for x in range(1,Yearloops):
    newsalary = newsalary*(1+calculation1)
    print(x + 1, newsalary )

我在循环外打印了第一年，因为根据您的规格，我们还不想计算增长。

这似乎是一个相当直接的解决方案，供您参考：当您不打算使用正在迭代的项时，通常会使用for _ in something。

print('Enter the starting salary: ', end ='')
SALARY = float(input())
print('Enter the annual % increase: ', end ='')
ANNUAL_INCREASE = float(input())

Yearloops = int(input('Enter number of years: '))

for _ in range(Yearloops):
    print(SALARY)
    SALARY += (SALARY / 100) * ANNUAL_INCREASE
